鼓室的

The crus breve incudis is an important marker for operation. The anatomical position of PE is constant. The depth of PTC affects the procedure for cochlear implant surgery via mastoid process-facial recess approach. The location of vestibular window and the round window is relatively stable, so the stapes head can be used as a reference for drilling scala tympani.

结论砧骨短脚是手术的重要标志；锥隆起解剖位置恒定；后鼓室的深浅对该进路的人工耳蜗植入手术的难易程度有重要影响；前庭窗与圆窗的位置关系相对稳定，因此镫骨头可作为参照标志来确定鼓阶钻孔的位置。

Thirty two cases of middle ear cholesteatoma limited in epitympanum were treated.

目的 ：探讨提高局限于上鼓室的胆脂瘤型中耳炎疗效的手术方法。

The positive pressure of 6kPa was given via mask to the nasopharynx of the testee, while the control took normal breath.

被试者经面罩给予6kPa的鼻咽部正压，对照者正常呼吸，高压舱以0.5kPa／s的速率增压至5kPa，被试者和对照者均不采用其他任何主动或被动开放咽鼓管的措施，测鼓室腔压力；高压舱以同样速率增压至20kPa，被试者条件不变，对照者可进行主动或被动开放咽鼓管的措施，测鼓室压。

Methods: 8 patient of cholesteatoma tympani with 10 ears were irrigated with 3% Purslane after oto-endoscopic.

对8例10耳单纯上鼓室胆脂瘤或伴外耳道后上壁部分缺损、CT示鼓窦、鼓室及乳突有软组织影的胆脂瘤型中耳炎采用耳内镜手术配合3%马齿笕溶液冲治疗。

Purpose To study the multi-view CT technique for tympanum examination.

目的 探讨鼓室的多角度CT显示技术。

Methods60 sides of 30 dry temporal bone specimens had their mastoids outlined by an electric drill, and then the related structure of the posterior tympanum was exposed. Distances of the related anatomic structures were determined under surgical microscopy.

方法取成人30个干性颅骨的60侧颞骨，用耳科钻完成乳突腔气房"轮廓化"，充分暴露后鼓室的各相关结构，在手术显微镜下进行解剖学观察，并对有关结构之间的距离进行测量。

Ten patients with temporal bone fracture and trauma of ear,whose CT scan of temporal bone showed that Malleoincudal joint irregular shape in the axial view and incudostapedial joint dislocation in the coronal view,were included in this study,Virtual endoscopy showed Malleoincudal joint separation,incudostapedial joint dislocation and interruption,ossicular chain disruptio...

虚拟耳镜示锤砧关节分离，砧镫关节脱位，听骨链中断。手术经颞线下开放上鼓室，保留完整的外耳道后上壁，充分暴露上、后鼓室和听骨链，检查并行听骨链成形术。结果：砧骨长脚骨折1耳，将砧骨改型后行锤-镫连接术；锤砧和砧镫关节脱位6耳，砧骨完全脱落3耳，行砧骨复位双关节固定术。10耳均行上鼓室进路鼓室探查术，术后语频听力平均提高25~50dB。结论：完壁式上鼓室进路鼓室探查术治疗外伤性听骨链中断疗效满意。

Results Of 355 ears in 200 children with secretory otitis media, 240 ears exhibited type B tympanogram and 115 ears type C. Removal of hydrotympanum was performed in 355 ears. There was no significant difference in total obtaining liquid rate (P＞0.05). However, there was very significant differences in obtaining mucus rate, stapedius muscle reflex and recurrence rate (P＜0.01), and a significant difference in obtaining serous rate (P＜0.05). There was no misdiagnosis and missed diagnosis in 200 sick children undergoing acoustic immitance determination.

结果 200例（355耳）分泌性中耳炎患儿呈B型鼓室导抗图240耳，C型鼓室导抗图115耳，分别对其抽出鼓室积液，它们的总得液率无显著性差异（P＞0.05），但其得粘液率、镫骨肌反射、复发率有极显著性意义（P＜0.01），得浆液率有显著性意义（P＜0.05）；在接受200例声导抗检查的患儿中，无1例发生误诊及漏诊。

Methods60 sides of 30 dry temporal bone specimens had their mastoids outlined by an electric drill, and then the related structure of the posterior tympanum was exposed. Distances of the related anatomic structures were determined under surgical microscopy.

方法取成人30个干性颅骨的60侧颞骨，用耳科钻完成乳突腔气房&轮廓化&，充分暴露后鼓室的各相关结构，在手术显微镜下进行解剖学观察，并对有关结构之间的距离进行测量。

Ordinary no destruction , the ossicular chain can be erosions and destruction , but more slight and no transitional .the major CT findings in simple chronic middle ear on 2 patients were soft tissue in middle ear cavity ,and 1 patient findings hydropneumo, the bone of tympanic cavity cirrhosis ,no destruction .

其它征象包括乙状窦、鼓室盖、水平半规管、面神经管水平段骨质破坏。29例肉芽肿型中耳炎CT表现为中耳腔内的软组织密度影，部分有液平，鼓室壁增生、硬化，骨质破坏少见，听小骨可出现吸收破坏，但程度较轻，一般无移位。2例单纯型中耳炎表现为中耳腔内的软组织密度影，1例有液平，鼓室壁骨质硬化，无骨质破坏。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
